SWITCH-SIGNAL.

Specification of Letters Patent.

Patented Dec. 12, 1905.

Application filed April 6, 1905. Serial No. 254,125.

To aZZ whom it may concern:

Be it known that 1, JOHN O.WIGMAN, a citizen of the United States, residing at Greenbay, in the county of Brown and State of Wisconsin, have invented certain new and useful Improvements in Switch-Signals, of which the following is a specification.

My invention relates to signals for indicating the condition of a switch to approaching hereinafter and illustrated in the accompanying drawings, in which Figure 1 is a plan view showing the casing inclosing the mechanism of my invention with'its cover removed, so as to disclose the operative parts of the circuit-closer; Fig. 2, an end view with the casing broken away, and Fig. 3 a side view with the casing removed and the operating-rod and its casing in section.

In the drawings similar reference characters indicate corresponding parts throughout the several views.

A represents the base of my improved switch-signal, upon which is mounted a casing B, made of any suitable material and is designed to protect its contents from the weather. Mounted at one end of base A is a lever C by means of a standard 0, being secured to said standard by a screw 0 Said standard 0 should be insulated from base A in any suitable manner. At the opposite end of base A from standard 0 is mounted another standard D, and secured to said standard D are posts E and F, the post E be ing insulated from standard D.

G and G represent set-screws mounted in posts E and F, between which oscillate the end of lever O.

H represents an eXpansible coil-spring secured to a post I, mounted on base A and insulated therefrom, the other end of said spring bearing against lever C to hold said lever nor mally out of engagement with screw G.

J represents a tube secured in the side of easing B and in the web of the main track K, and L a rod mounted in said tube, having one end bearing against the switch point M, while on its other end is an insulator-button N, which bears against lever C.

0 represents a suitable signal, such as a red light, and P a battery to energize said signal, the circuit from the battery to the signal being through wire Q to screw 0, then through lever C, set-screw G, post E, wire R to the signal, and by wire S from the signal back to the battery.

Instead of a light-signal a hell or other device may be substituted, and it will be understood that by posting the signal adjacent to the track it will serve to warn the engineer of the condition of the switch, or if placed in the station or switchmans booth it will warn the operator that the switch is set or fails to operate to open the main-line track.

Having thus described my invention,what I claim is 1. A circuit-closer for switch-signals, comprising, in combination with the switch-point, a bar secured to said switch-point, a lever mounted to oscillate in a horizontal plane and positioned to be struck by said bar, electrical connections with said lever and a contact-post in the path of the oscillation of said lever, and means to normally hold said lever out of contact with said post, substantially as shown and described.

2. A circuit-closer for switch-signals, comprising in combinationwith the switchpoint, a bar secured to said switchpoint, a lever mounted to oscillate in a horizontal plane and be struck by said bar, a contact-post arranged in the path of said lever, a suitable signal, electrical connections between said signal and the lever and contact-post, and an expansible coil-spring to normally hold said lever out of contact with said contact-post, substantially as shown and described.

3. A circuit-closer for switch-signals comprising in combinationwith the switch-point, a bar secured to said switch-point, a base suitably mounted adjacent to the switch, a lever mounted on said base and adapted to oscillate inahorizontal plane, the end ofisaidjbar with the set-screw in the last-named contact- 10 adapted to strike saidlever,a standard secured post, substantially as shown and described.

to said base, posts secured to said standard In testimony whereof I hereto aflix my sigon each side 05 the 651d of said levili, setnature in the presence of two witnesses.

screws niounte in sai osts, a suita e signal and battery for energizing said signal, the JOHN WIGMAN' lever in circuit with the battery and one of Witnesses:

the contact-posts with the signal, and a coil- J. F. MARTIN, spring to hold the lever out of engagement I. I-I.' \I. WIGMAN.
